I ran a repeat of an optimization function I ran last week, but my outputs have changed as of today. I use the interior-point solver via the lsqlin() command. I do not really understand why. Any advice or suggestions?

Since v9.0 was R2016a, it's worth asking:
Do you really mean version 9.0, or do you mean 9.9?
What version/release did you start with?
The release notes don't describe every detail that might potentially contribute to numerical differences in results.

I have MatLab R2019b version 9.7 and Global Optimization Toolbox R2019b version 4.2
I'm not exactly sure what version I started with, but I am assuming it would be version 9.6. I do know it was R2019b
